The DateDiff extension adds the #dates
parser function that returns a list of intermediary days.
Usage
The #dates
parser function comes with two parameters |StartDate
and |EndDate
which is used as follows:
- Syntax
{{#dates:
|StartDate=2016/10/01
|EndDate=2016/10/02
}}
- Result
2016-10-01T00:00:00+02:00,2016-10-02T00:00:00+02:00
Examples
A typical use case is events in a semantic setup that span multiple days. To have the events appear on all days on a calendar provided by the Semantic Result Formats extension, you would use something like (requires the ParserFunctions extension):
{{#ifeq: {{{recurring}}}
|no
|{{#set: Has date={{#dates: |StartDate={{{from}}} |EndDate={{{till}}} }} |+sep=, }}
}}
Number of days between two days (requires the Arrays extension):
{{#arraydefine:days
|{{#dates: |StartDate=2015-04-01 |EndDate=2015-04-10 }}
}}
{{#arraysize:days}}
